A woman riding an electric scooter has been killed in a crash with a lorry in south London.
The 35-year-old was pronounced dead at the scene at the Queen Circus roundabout, Battersea following the crash at about 08:30 BST.
A Metropolitan Police spokeswoman said her next of kin had yet to be informed and no arrests had been made.
In July last year a cyclist was killed at the roundabout after being hit by a bin lorry.
A London Ambulance Service spokeswoman said: "We sent an advanced paramedic, two ambulance crews, an incident response officer and two medics in cars to the scene, with the first of our medics arriving in under four minutes.
"Sadly, despite the extensive efforts of medics, a woman died at the scene."
Transport for London and Wandsworth Council redesigned the roundabout in 2015, which trialled the use of raised kerbs and separate traffic lights to keep cyclists and vehicles segregated at junctions.
Concerns had been raised that the new layout was too complicated.
While the cause of the crash is unknown, e-scooters are illegal to ride on public roads, including in cycle lanes or on the pavement.
A Department for Transport spokeswoman said: "We extend our deepest sympathies to all those involved in this tragic incident, and fully support the police as they carry out their investigations.
"Safety is at the heart of all our road laws and it is important that retailers continue to remind people at the point of sale that it is illegal to ride e-scooters on public roads."
An electric scooter, or e-scooter, is similar to a traditional children's scooter but has a motor attached.
